What standard hand signal represents 'Travel (one track)'?

The standard hand signal that represents 'Travel (one track)' is depicted by an upward arm raised with the hand open and moving side to side, indicating the direction of movement on a single track. This signal is crucial in rigging operations, especially when guiding equipment that may be moving on a specific rail or track.

The choice that refers to 'Travel (one track)' specifically communicates the intent to move along a designated path without ambiguity. This is particularly important in rigging scenarios where precise navigation is necessary to ensure safety and efficiency.

In contrast, other options may encompass broader or different commands that do not specify the single-track movement. For example, a general command might not clarify the limitation to just one track, potentially leading to miscommunication or improper movements that could jeopardize safety. Therefore, the clarity provided by the specific designation of the hand signal for 'Travel (one track)' is vital in the rigging context.
